A quick connector coupling for a fluid line includes a hollow female connector body which receives a tubular male member with a raised annular upset. A retainer is demountably coupled to the connector body. The retainer includes two spaced beams which extend through slots in the connector body from a cross member postioned outside of the connector body. The beams are positioned between the upset and an end of the connector body, and have a relaxed spacing less than the upset diameter such that the male member is secured in the connector body. A release protrusion projects from each retainer beam between the cross member and the connector body. The release protrusions have cam surfaces cooperable with an external surface of the connector body to spread the retainer beams apart when the cross member is pressed toward the connector body.
Cette invention concerne un raccord rapide pour circuit fluidique, qui comprend un corps femelle creux dans lequel se loge un élément mâle tubulaire comportant une nervure annulaire. Un dispositif de retenue amovible est monté dans le corps du raccord. Ce dispositif comprend deux branches espacées qui passent dans des fentes ménagées dans le corps du raccord et une traverse reliant les deux dites branches et demeurant à l'extérieur du raccord. Les deux branches de ce dispositif se trouvent entre la nervure annulaire du tube et une extrémité du raccord. Leur espacement au repos étant inférieur au diamètre de la nervure annulaire du tube, ils retiennent celui-ci à l'intérieur du raccord. Les deux branches du dispositif comportent une partie en saillie entre la traverse qui les relie et le corps du raccord. Ces parties en saillie présentent une rampe qui, au contact d'une surface extérieure du raccord, force l'écartement desdites branches lorsque une poussée est exercée sur la traverse du dispositif de retenue, vers le raccord.
